Python list append() usage and example

List methods in Python

The append() method adds an item to the end of the list.

The append() method adds a single item to the end of the list.

The syntax of the append() method is:

list.append(item)

append() parameter

This method has one parameter

• item -Item to be added to the end of the list

The item can be a number, string, dictionary, another list, etc.

append() return value

This method does not return any value (returns None).

Example1: Add element to list

# Animal list
animals = ['cat',　'dog',　'rabbit']
# Add monkey to the animal list
animals.append('monkey')
# The animal list after appending
print('New animal list:　', animals)

Output result

New animal list:　　['cat',　'dog',　'rabbit',　'monkey']

Example2: Add list to list

# Animal list
animals = ['cat',　'dog',　'rabbit']
# List of wild animals
wild_animals = ['tiger',　'fox']
# Add the wild animal list to the animal list
animals.append(wild_animals)
print('New animal list:　', animals)

Output result

New animal list:　　['cat',　'dog',　'rabbit',　['tiger',　'fox']]

It is important to note that in the above program, the items (wild_animals list) have been added to the animals list.

If you need to add items from a list to another list (not the list itself), you need to useextend() method.
